The test can be carried out with samples from the alleged father and the child, however we do suggest including the Mother’s sample for a more accurate result. There are cases where the alleged father cannot take the DNA test – perhaps he may be entirely unaware of it or even deceased. In such cases, EasyDNA can still provide answers to your questions by offering a range of relationship DNA testing services. Relationship DNA tests can establish paternity by testing the relatives of the alleged father such as siblings, parents or grandparents.
